If you like reading, then next year you could try combining your enjoyment with some financial planning by investing in your favourite books. I think a lot of people are looking for different investments and moreover something that they can actually enjoy as well as just seeing a statement with an amount of money in a bank account, and also things like 'Harry Potter', or even adults are enjoying that, although obviously it's directed at children. It's a way of having a different sort of investment. Of course it's not just really old and rare books like these that have value. Adrian, what's a popular area to collect in at the moment? Modern first editions, children's books, by far and away the most popular. And you've got one here. What the 'Harry Potter', the film sequence is out, as we all know, first edition of the first book, only 300 printed. First edition because it goes numbering sequence down to one, and this one's inscribed by J. K. Rowling which helps a lot. This book is £25.000, published in 1525, first edition of 'Hypocrites', published in 1997. They have the same value. You pay your money, you take your choice. If you're thinking of starting collecting, what are a few simple rules? Buy what you like. Always buy the best condition you can afford. Don't buy books that are sun-faded like this one. These two books are the same book and this one's been left in the sun, totally devalued. That's £120, that's £40, so it really does devalue it. Don't buy books that have been written in, like this, unless it's the author's written, and if you're collecting books, don't write in them yourself unless you do it in pencil. Never price-clip a book, it devalues it. So, keep them in the dark, write in pencil, don't price-clip. And never read them. Never read them, read the paperback. That's the trick, and build a good relationship with a dealer. I would say that, wouldn't I? But it's not a bad idea to find a dealer, especially if you're a James Bond fan. Next year it's Bond's 50th birthday, and first editions are expected to fetch anything from £5,000 to £20,000. Marcia Hughes, BBC News.
